30 Claims.

The present invention relates tc window channels, such for example, asthose employed for supporting or guiding windows or window panes invarious vehicles, such as automobiles, aeroplanes, motorboats, and thelike.

One object of the invention is the provision of an improved windowchannel or channel-like structure which is of simple construction andwhich can be manufactured at a relatively low cost.

A further object of the invention is to provide a unitary window channelhaving improved and advantageous forms of construction which render itserviceable and eiiicient as supporting or guiding means for a window orother form of closure.

A further object of the invention is to provide an improved windowsupporting or guiding structure designed for cooperation with a vehiclewindow when it is in substantially closed position to afford one or moreVentilating openings whereby to insure an increase in the circulation ofthe air within or through the vehicle body to more effectively ventilatethe same.

A further object of the invention is the provision of a new and improvedchannel or channellike structure formed of parts or sections which canbe conveniently assembled and readily connected one with another wherebyto provide a unit for supporting either a fixed or a movable part such,for example, as a window or other closure.

A further object of the invention is the proviw sion of an improvedstructural element designed to serve both as cushioning means for aWindow and as means for connecting parts of a supporting or guidingstructure for the window.

A further object of the invention is to provide an improvedself-contained window channel ready for direct application to a vehiclebody and one which includes exible parts permitting the channel to bereadily bent or shaped to correspond to the shape of the window or othera parts with which it may be associated.

Tc these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the speciiication.

The same reference numerals throughout the several views indicate thesame parts.

The channel of the present invention may comprise either a rigid or amore or less flexible body sufliciently stiff to be substantiallyself-supporting when placed in a window frame under normal conditions ofuse. In other words the main channel body may either be of an all metalconstruction or of fabric woven from non-metallic bers, or it mayinclude in part at least a metallic filament such as wires woven intothe fabric to afford added stiffness without unduly decreasing theexibility of the channel.

It will be understood that if it is preferred to construct the mainchannel entirely of metal, the

latter may, if desired, be of a nature which will permit it to be bentto afford different shapes depending on the shape of the frame or otherparts with which it is to be associated.

This is true also of the connecting strip or securing element shown inFig. 8 and employed as a means for uniting the side members of thestructural channel shown in section in Figs. 6, 12, and 14, thedifferent forms of which are shown applied to the intermediate portionof the main channel in Figs. 4, 10, and 13, respectively.

Referring now to Fig. 1 of the drawings, there is shown at l0, forexample, a vehicle door frame equipped with a window glass Il arrangedto l5 slide up and down to open and closed positions.

In the position of the glass shown in Fig. 1 there are afforded theoppositely disposed Ventilating openings i2 for increasing thecirculation of the air within or through the vehicle body to effectbetter ventilation of the same.

The door frame E3 shown in Fig. 2 is similar to that shown in Fig. 1,and has a window I4 free to be moved up and down therein which, when inthe position shown, affords Ventilating openings I5 at its uppercorners.

Likewise the door frame l5 is provided with a sliding window II whichwhen moved to the position shown affords Ventilating openings i8 at itsupper corner portions.

A cross section of one of the side members of the door frames shown inFigs. 1 to 3, inclusive, is illustrated more or less diagrammatically inFig. 15 which affords an opening I9 for the insertion of the main windowguide channel, shown generally at 2D and 20a in Figs. 4 and 10. Thechannel 2D comprises the oppositely disposed side portions 2l and thetransverse connecting portion 22, Fig. 4.

The construction of the channel shown in Fig.

15 corresponds generally in cross section to the Window channeldescribed 'and claimed in the pending application of Charles P.Schlegel, Serial No. 660,402, filed March 11,1933, (novv' Patent No.2,012,354, granted August 27, 1935)' which embodies a completeYdisclosure of the manner of constructing this form of channel. The warpstrands of the body of the channel are indicated diagrammatically at 23,and the transverse or weft strands, which may constitute metalliclaments, are indicated diagrammatically at 24. However, any of thestrands may be made from either metallic or non-metallic material sothat a part or all of the Warp strands and a part or all of the weftstrands may be metallic if desired.

The channel body is preferably provided with -suitable cushioning orlining means for supporting and cushioning the window or glass embracedby the channel and for providing a smooth run- Wly for the glass if itis of the sliding or movable variety. The lining means may be formed ofpile or any other` suitable cushioning material and may be formed as apart of the channel body or as a Separate piece or pieces secured withinthe Channel body as desired. Preferably the lining comprises strips 25of relatively long stiff pile Woven integrally with the channel body,the strips extending longitudinally along the inner surfaces of the sideportions and of the back or bottom portion of the channel, as indicateddiagrammatwally in Fig. 15.

The channel construct lion also includes rela tlvly large Warp strand: i23a at its outer edges which serve to reinforce and enlarge Sad edgesthe latter being embraced and protected by the l'llshl'ng or bead-likememl l 26 formed of Sheet or other suitable material and serving tostii'en the edges of the channel and maintain them in proper alinement.

The window il, shown at Fig. 1, has an arched or rounded portion Het atits upper end which.. 5 when the window is completely closed, extendswithin the upper transverse connecting portion.v of the door frame inwhich position the rounded corner portions lib of the window lie withinthe curved corner portions of the main channel 2G. 10i

In order to permit the Window to be raised to full closing position inwhich it will serve to close the Ventilating openings l2, the transverseconnecting portion 22 of the channel is provided with an opening 21 inits bottom or horizontal 15' Wall, Fig. 6, through which the archedportion'. Ha of the window is moved when elevating the window to itshighest position.

Furthermore a receiving channel or channellike member for the archedportion of the window 20 is superimposed upon the transverse connectingportion 22 of the window channel in registry with the opening 21therein, said receiving member being indicated generally at 29 in Fig.4. The receiving member is preferably made to corre- 25 spond in shapeto the upper arched portion Ila of the window as indicated by dottedlines in Fig. 1.

The opening 2l in the transverse connecting portion 22 of the mainchannel is preferably 30 formed by slitting said portion longitudinallyand centrally thereof and bending outwardly the portions 33 intoupstanding spaced relation, as best shown in Fig. 6. The outwardly bentportions are utilized as supporting means for the 35 channel-shapedwindow receiving member 29, the side Walls 3i of each of which has itslower edge bent back upon itself and rebent to form: a grooved orchannel-shaped portion 32 for receifv'- ing the corresponding upstandingparts 3B ai 40 the main channel, as best shown in Fig. 6.

The side walls Si of the glass receiving member 29 are provided withlaterally and inwardly extending spaced flange-like parts 33 lyingopposite each other in pairs and beneath which is 451 extended aconnecting strip 3G having a body portion of a width substantially equalto the distance between the side members 3i of the glass receivingmember 29. The connecting strip 34 is provided with a series oflaterally projecting 50 tongue-like` securing members 35 at the oppositesides thereof which are extended through the openings 36 afforded by thespacings between the flange-like members'33 of the side walls of thewindow receiving member 29, said tongue-like 55 receiving members beingbent into engagement with the exterior surfaces of said side walls, asshown in Figs. 4 and 6. The connecting strip 34 can be readily assembledin position between the walls 3i of the channel-shaped member 29 be- G0fore the latter is connected with the main channel and united with saidmembers to form a complete unitary structure which can be readilysecured upon the main channel by positioning the grooved orchannel-shaped portions 32 of 65 said unit upon the upstanding portions33 of the transverse portion of the main channel 20, said channel-shapedportions being preferably clamped upon the supporting portions 30 tofirmly secure the window receiving member upon 70 the main channel. Thewindow receiving member 2:7 is also secured upon the main channel bymeans of the short extensions 3l on the ends of the connecting strip 34which rest on the back of the transverse portion 22 of the main chan- 75nel, as shown in Fig. 4, and which are secured thereon preferably bymeans of the rivets 38, as shown in Fig. 5.

Cushioning means for receiving the arched portion Ila of the window IIis secured Within the recessed member 29 which preferably comprises awoven strip of fabric 39 shown diagrammatically in Figs. 6 and 9, whichis provided with a cushioning pad 40 also indicated diagrammatically andpreferably formed of relatively long stiff pile suitable for obtainingthe desired cushioning action. The pile is preferably interwoven withthe strands of the strip 39 but may be otherwise connected with andsupported by said strip if desired. The woven strip 39 is formed of thewarp and weft strands 39C and 39d, respectively, and is preferablyprovided with enlarged portions 4I at its opposite edges formed of oneor more warp strands or cords Mc, as

i shown in Fig. 9. 'I'he strip 39 is supported upon the inner face ofthe metal strip 34 by the inwardly turned portions 42 thereof which liebetween the tongues 35 of the strip, as best shown in Fig. 8, saidinwardly turned portions envelopf ing the enlarged portions 4I of thecushioning strip and also serving to lend the desired degree ofstiffness to the connecting strip which is formed of a relatively softmetal permitting the strip to be readily bent to any shape desiredwhereby it may be made to conform to the shape or contour of the sectionor parts with which it is to be associated. The strips are preferablyiiat when completed and readily conform to the contour of the curvededges of the side walls 3| of the member 29 when applied thereto.

The main channel shown in Figs. 2 and 10 is indicated generally at a.and is provided with vertically extending side portions 2|a and atransverse connecting portion 22a, the shape and construction of thischannel being the same as the channel 29 as previously stated. Either ofthe channels, as previously stated, may be formed entirely of sheetmetal or other suitable material rather than of woven fabric, ifdesired.

The transverse portion 22a of the channel is provided with an opening21a for the passage of the upper portion I4a. of the window I4 shown inFig. 2. The opening is preferably formed by slitting the base or back ofthe channel section longitudinally of its center and turning outwardlythe upstanding spaced portions 30a of the channel, as shown in Fig. 12.The channel is also provided with window cushioning pads a correspondingto the pads 25 of channel 20. The window receiving member 29a, anenlarged plan View of which is shown in Fig. 11, is of substantially thesame design as the member 29, and as many of the parts of the twodesigns are alike in construction, they have been given the samereference characters with the addition of the letter a to the severalparts of the member 29a., which will be readily understood from thedescription of the corresponding parts of the Window receiving member2S.

However, it will be noted that there is a difference in the shapes ofthe members 29 and 29d, the former being curved as shown in Fig. 4, andthe latter being fiat on top for the greater portion of its length andhaving a beveled or inclined portion 42a at one end thereof. A furtherdiierence between the two window receiving members in question is thatthe one shown in Fig. 10 does not have the securing parts 31 of the oneshown in Fig. 4. It will be further understood that the differencesbetween the members 29 and 29d, is due merely to the difference in thecontours of the upper extremities of the windows II and I4, shown inFigs. 1 and 2, respectively.

The receiving member 29h for the upper portion Ilo: of the window I'I isshown in elevation in Fig. 13 and by dotted lines in Fig. 3. Since themember 29h is substantially the same in construction as the member 29a,it has been given the same reference character with the exception thatthe letter b has been substituted for the letter a in designating anddescribing the parts of the member 29h, it being understood that thedescription of the former will suffice for the later, the one differencebeing that the channel-shaped members 32a at the lower edges of the sidewalls 3Ia are omitted from the side walls 3Ib of the member 29h', aswill be seen from Fig. 14.

The lower edges of the sid-e walls @Ib of the window receiving member2912 are extended within suitable anti-rattling members indicatedgenerally by the reference character 43, Figs. 13 and 14. Theanti-rattling member is formed of a metal section 44 bent back uponitself to afford l a receiving channel for the side walls Sib of themember 29h and has a strip of woven textile fabric 45 extending aroundits exterior surface and secured by bending the extreme edges of themetal sections down upon the edges of the fabric strip as indicated at46. The woven fab-ric strips are provided on their inner faces withsuitable cushioning means for the window, such, for example, as theresilient pads 4l preferably formed of relatively long stiff pile woveninto the textile strip 45 and projecting for a substantial distancetherefrom. The cushioning means, however, may, if desired, be formed andconnected with the textile strip in any suitable manner other than thatdescribed. Preferably, however, the anti-rattling members 43 areconstructed generally in accordance with the anti-rattling strips orsections described and claimed in my cepending applications, Ser. No.697,315, filed November 9, 1933, for Window cushioning construction, andSerial No. 718,803, led April 3, 1934, for Anti-rattling strip.

The anti-rattling members 43 and the window receiving member 29h carriedthereby form a unitary structure which may have its opposite ends placedin abutting relation with respect to and suitably connected with theends of the oppositely disposed channel members 2lb which form acontinuation of said unitary structure to afford cushioning and guidingmeans for the window I1, shown in Fig. 3, in which construction thecentral portion Ila of the window extends within the receiving member29h when the windown is completely closed, in which position theVentilating openings I8 are also closed.

The channels 2lb are preferably the same in cross section as thechannels 29 and 29a., except that the bead-like members 26 of the latterare omitted.

If preferred, the window receiving unit formed of the connected members29h and 43 may be secured and supported within the door or window frameI6 by the use of screws or nails driven through the relatively softmetal strip 34h into an overlying portion of the frame, not shown. Thechannels 2lb may likewise be secured within the side members of the dooror window frame I3 as shown in Fig. 15.

It will be understood that the metal strips 34, 34a, and 34h, similarlyconstructed in each of the designs shown in Figs. 4, l0, and 13, can bereadily bent to correspond to the shapes or contours of the partsconnected thereby and that they can be employed as a connecting meansfor other parts, not shown, having other shapes regardless of whether ornot the cushioning strips 40, 40a and 4gb are applied thereto. The metalstrip, either with or without the window cushioning means comprises auseful and advantageous connecting element for oppositely disposed partsand affords a new and improved article of manufacture.
